Evaluation of three types of platforms in single-incision laparoscopic surgery for performing transanal endoscopic microsurgery (SILSTEM).

Background/Aims: Transanal endoscopic microsurgery using a platform for single-incision laparoscopic surgery (SILSTEM) is safe for excising rectal lesions. W e tested three types of platforms. Methodology: Nine patients underwent SILSTEM by one surgeon. Tumors located 5-15 cm from the anal verge were eligible. After Measuring their dimensions, length, and trocar channels, the platforms tested were the SILSTM port (SP), EZTM access (EA), and GelPOINTTM Path (GP). Clinicopathology, intraoperative parameters, and postoperative outcomes were recorded. Results: Six men and three women (median age 63 years) underwent SILSTEM us platform SP in three patients, EA in four, GP in two. Median operation time was 128 min (range 71-313) Median blood loss was 3 ml (range 1-71). Pathology Confirmed adenocarcinoma in five patients, in three, and carcinoid in one. Patients were within 2-13 days postoperatively. There was no postoperative fecal incontinence or soiling. Overall median follow-up was 13.3 months (range 1.3-27.2). There were no recurrences. Conclusion: SILSTEM can effectively resect rectal tumors using any of three platforms. Largel prospective trials are needed to define the advantages disadvantages, and indications for each platform and to draw conclusions regarding operation time, anorectal function, and costs.
